| 摘 要： | 依据全球气溶胶自动观测网在极地区域的观测,对以下问题进行了讨论:(1)温度订正在极地气溶胶光学厚度观测中的重要性及订正方法;(2)在极地进行仪器常数标定的可行性分析及温度效应的影响;(3)利用天空散射光观测反演气溶胶微物理和光学特性参数(粒子谱分布、散射相函数、复折射指数、单次散射反照率等)时,关于观测几何选择的问题,以及针对极地区域气溶胶特性的初步反演结果。这些研究可以为中国未来在两极地区开展基于自动太阳-天空辐射计的气溶胶地基遥感观测提供参考,为极地区域气溶胶卫星遥感及气候效应评估等研究提供重要支撑。

| Abstract: | This paper introduced several important issues on applying ground-based automatic sun-sky radiometer CE318 for aerosol remote sensing in Polar Region. Due to extremely low temperature and special weather condition like big wind in Polar Region, scientists usually meet some particular problems when performing aerosol remote sensing based on direct sun and diffused sky light measurements. Following sun-sky radiometer CE318 measurements at polar region, this paper discussed (1) the importance and application of temperature correction to aerosol optical depth measurements in polar region; (2) temperature effects when performing instrument calibration in polar region using Langley plot method; (3) using diffused sky light in the retrieval of aerosol micro-physical and optical properties to choose observation geometry. These studies can provide reference for performing ground-based aerosol remote sensing using automatic sun-sky radiometer in Polar Regions, and support satellite remote sensing of polar aerosol as well as assessment of its climate effects. |
